Hair testing is highly regarded as an effective means to detect drug and alcohol consumption. Hair retains a long-term record of substances by embedding biomarkers in its fibers as it grows. When samples are cut near the scalp, they can reveal drug or alcohol use over a period of up to three months. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch section containing roughly 200 hair strands (comparable to the thickness of a #2 pencil) gathered closest to the scalp yields 100mg of hair, optimal for screening and confirmation testing. For additional tests like EtG or those beyond 10 panels, a specimen of 150mg is suggested. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair isn’t accessible, an equivalent quantity of body hair can be used. "Head hair" pertains exclusively to scalp hair, whereas "body hair" covers other varieties (facial, axillary, etc.).
Process Overview
The procedure for laboratory processing of drug test outcomes includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase where samples are input into a lab’s database. This process entails verifying the sample’s proper sealing and shipping, allocating a unique LAN (Laboratory Accessioning Number), and completing any leftover data entry not managed by an electronic chain of custody system.
Screening performs a preliminary assessment for drug abuse indicators. Though cost-efficient for eliminating drug use in most samples, a positive screen must be validated to be viable in court. Samples showing presumptive positives in Screening necessitate further confirmation.
For samples showing presumptive positives during Screening, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
GC/MS, GC/MS/MS, or LC/MS/MS are utilized to confirm any positive Screening results. Prior to confirmation, all presumptive positive samples are washed as applicable. The complete laboratory process from Accessioning to Confirmation undergoes review under the standards of CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Often termed "hair follicle tests", these tests actually examine the hair strand itself, not the scalp-anchored follicle.
In Centralia, WA, hair follicle testing offers distinct advantages over urine testing. While traditional urine tests are commonly used, hair testing provides superior detection accuracy due to a longer detection window, allowing for substance history review over a greater timeframe.
